Specific gene may play a causal role in heart disease independent of cholesterol levels

High cholesterol is the most commonly understood cause of atherosclerosis, a hardening of the arteries that raises the risk of heart attack and stroke.

Changes in OASI gene expression increases risk of Alzheimer's and severe COVID-19 infection

Previous research identified the interferon-responsive OAS1 gene as a risk gene for Alzheimer's disease. OAS1 is an enzyme that binds to double-stranded RNA and induces the conformation to create oligoadenylates. They also activate RNase L to break down RNA.

Research demonstrates multivalent nanobodies overcome SARS-CoV-2 variant mutations

In a recent bioRxiv* preprint paper, researchers isolated anti-RBD nanobodies from llamas and “nanomice” (they engineered to produce VHHs cloned from alpacas, dromedaries and camels).

New evidence supports the use of antisense oligonucleotides as feasible therapeutic strategy for MDS

Many cognitive neurodevelopmental disorders are a result of too many or too few copies of certain genes or chromosomes.

Genetic variation associated with COVID-19 outcome

Host genetics play a role in disease progression and prognosis. A paper recently uploaded to the preprint server medRxiv by Dubé et al. (1st March 2021) identifies several alleles associated with the gene natriuretic peptide receptor C (NPR3) that may impact disease severity.

Neanderthal gene can confer protection against severe COVID-19, finds study

A new study has detailed how some of the genes in the human genome inherited from Neanderthals appear to confer a protective effect against severe COVID-19.

Whole-genome study of IBD in African Americans reveals a different genetic risk landscape

In African Americans, the genetic risk landscape for inflammatory bowel disease (IBD) is very different from that of people with European ancestry, according to results of the first whole-genome study of IBD in African Americans.

Researchers find CXCR6 gene plays a role in COVID-19 severity

Researchers in the United States have conducted a study demonstrating that a gene called CXCR6 (C-X-C Motif Chemokine Receptor 6) may play an important role in determining the severity of COVID-19.

Clonally expanded plasma cell lineages in SARS-CoV-2 produce specific neutralizing antibodies

A new preprint research paper posted to the bioRxiv server provides a greater understanding of the aspect of humoral immunity against the virus – the plasma cells that pour out a flood of specific antibodies targeting various epitopes on the pathogen.

Study addresses multiple challenges of the pathogenesis of Huntington's disease

Recent genetic data from patients with Huntington's disease (HD) show that DNA repair is an important factor that determines how early or late the disease occurs in individuals who carry the expanded CAG repeat in the HTT gene that causes HD.

Study finds protective genetic associations with mild COVID-19

Using self-reported survey data, researchers have defined eight phenotypes associated with COVID-19 outcomes. Analysis of the data revealed possible protective genetic associations.

Researchers develop new computational method for studying genetic and environmental interactions

Researchers at Weill Cornell Medicine and Cornell University's Ithaca campus have developed a new computational method for studying genetic and environmental interactions and how they influence disease risk.

Blood group associated with cardiovascular events in COVID-19 patients

An illuminating new study by scientists at Harvard Medical School, USA, describes the correlation of such conditions with the ABO blood group. The team's findings may help assess the risk of COVID-19 patients for such complications, promoting early diagnosis and underscoring potential needs for preventive and therapeutic care where possible.

COVID-19 severity could be linked to genetic variance

A new study describes some potentially important genetic factors in the host that may shape the clinical symptoms and signs of the disease.

Autoimmune condition biomarkers promote SARS-CoV-2 viral entry, study finds

Researchers have reported that the autoimmune PTPN2 risk variant rs1893217 promotes the expression of the SARS-CoV-2 receptor, ACE2, and thus promotes cellular entry, which is mediated by SARS-CoV-2 spike S protein.

Neanderthal gene variant increases risk of severe COVID-19

Researchers in Germany have conducted a study showing that between 2 and 8% of people in Eurasia carry a genetic variant inherited from Neanderthals that significantly increases the risk of becoming critically ill with coronavirus disease 2019 (COVID-19).

COVID-19 genetic risk variants impact diverse immune cell types and severe disease manifestations

A team of researchers from UK and US used the DICE database and 3D cis-interactome maps to generate a list of target genes and immune cell types that are most affected by the genetic variants associated with COVID-19 severity.

Drinking obstructs a chemical that boosts attention

In a new paper, researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) report brain chemistry that may contribute to why drinkers have difficulty paying attention while under the influence.

Specific SARS-CoV-2 genomic variations are associated with higher COVID-19 deaths

A team of scientists from South Korea and the United States has conducted an interesting study to investigate whether mutations in the genome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can affect the severity of coronavirus disease 2019 (COVID-19). The study findings reveal that mutations in the viral spike protein and RNA polymerase complex can increase the risk of COVID-19 mortality.
